IMPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Fatent and making partici' thc same.`

1', GEORG-E WALTER BRoNsoN, of Ottawa, in the county of La Salle and State oi Illinois, have invented a certain Improvement in .Gultivators,of which thc following is a speciiication.

My invention relates tothe combining of' a if walking?7 and a rlding7 cultivator:inkopermachine, in t :such va manner that, beit" used in "either'\vay, itl V'makes as complete and eieient amaehineas ifit had been constrnetedior onlyfene purpose.' This object is attainedby making the drivers seat Ireiijiovable, and by providing slides oirwhich the beams ofthe plows can be moved forward or backward, according as the machine'k is tobe used fora walking or a riding cultivator.

'By means ot these slides, also, the' plows Amay be pulled back from under'the frame-when usediuwalk.. fing, thus giving the operator full -eedomffforhandlin'g' the plows.A Y

When a driver rides on a cultivator his seat must necessarily be behind, so that he may have hold ot the handles of the plow-beams. In this position the weight oi driver more than conuterbalances the weight of the tongue and attachments, and the machine is lia-blc to tip over backward. l

A common way. to prevent this is to attach a weight to the end of the tongue, just heavy enough to balance the machine.

When a cultivator Ais designed for riding only the machine is constructed with the beams more forward and the seat nearer to the wheels, in which case the weight of the driver, acting on a shorter lever, is no tsufticient to tip the machine. v But when a culiivator is constructed in .this manner it cannot weil be used as a \'valking.plow, even when the seat is removed, because the -plow's would be so heavy ,forward as to make it very hard on. the horses neck. I

Another method is to throw the wheels forwar, d, when the machine is to be changed from a riding to a walking plow, but I claim that my device, asl hereafter described, is much better adapted to vthe pui-pose, white it gives the further advantage t ot' euabiing thcv operator to give to the shovels a pitch or inclination either toward the inside or outside, which is found to be ver-y convenient, as my cult-ivator, lin this capacity, does the same work as a gopher or longshovel machine, and thus saves the cost of a gopher to those that wish to work with the one and with the-other, alternately. Figure 1 in the drawing is a side' view of the machine as adapted for walking, `one wheel being relnoved in order to better exhibit the improvement.

Figure 2 lis aside view ot" the machine as adapted -for walking, one wheel being also removed to aiford a better view of the improvement.

Figure 3 is a horizontal view of the machine, adapted tor ruling.

ing.

Figure 4 is a section through Va b, iig. i3. Figure 5 is a section through 'c d, iig.` A cross-beam, A, has attached to itfthe tongue B. At each endv of the cross-beam A are attached, the

castings O O, onto which the wheels'D'D are attaehed by meansrof permanent axles, l

These castings vGr O have hollow casings,finto which the two rails F F supporting the seat :G are fitted, so as to -slide in and stay withoutany otherlfasteu- Forward of the cross-beam and attached'fpar'tly thereto and partly to the tongue B, are the slide-bars Ou these bars slide thehoxesl Lhavingbelowthe round stems J on which-swing the plow-beams The 4slide bars KI I .HJ-extend enough forward io allow the plowvhandles L vlllrtofcoine withiirconvenv ient reachfof the driver seated on the seat G,this seat being placed just inthe V'position in which the weight ot' the driver will eonnterbalance the'tbrward part'of'thc machine.

" The fastening of the slide-bars lH H is such, byV

means of a loose bolt throughthe tongneB, and ex tensions of the ,bars througlrfthe crossbeam A,l `that,- by loosening the nuts -M M, -the`slide-bars H H-may be twisted in or ont, thus ygiving the shovels N N a pitch like a gopher cnltivator.

The plow-beams K K are hung byrmeans ot chains,v l) P, to their desired pitch.

The beams K K have each a wrought.- iron extension, Q Q, turned outward, so as to aiiord more room for the feet of the driver, the seat being very lewin this machine.

The 'plow-handles L L are provided with sliding braces, R It, the object of which Vis to allow the operator to pnt the handles .on one ,side when he walks behindthe machine.

The whitetree S has two sets of hitching-hooks.

The upper vset:,\.;^l. T; is, used in riding, when the machine is balanced, while the lower set UU is used for walking, as they pull upward and assist in balancing the machine. v

What I claim as my invention isA 1; The slide-bars H H, in combination with the boxes I I, the stems J' J, the chains P l), and the plow-beams K K, substantially as and for the purpose described.

2. The sliding braces 1t It, in combination with the plow-handles L L and, the plow-beams K K, substantially as described.
